Method Detail

toString

public String toString()

Overrides:

toString in class Object

createMethodInvocation

findOneWayAnnotation

protected Pattern findOneWayAnnotation(Method method)

Finds the oneway annotation in priority order; look for method level annotations first, then the class level annotations, then super class annotations then interface annotations

Parameters:

method - the method on which to search

Returns:

the first matching annotation or none if it is not available

getPatternAnnotation

protected Pattern getPatternAnnotation(AnnotatedElement annotatedElement)

Returns the pattern annotation on the given annotated element; either as a direct annotation or on an annotation which is also annotated

Parameters:

annotatedElement - the element to look for the annotation

depth - the current depth

Returns:

the first matching annotation or null if none could be found
